Hello,
I think this simple screen will resume my problem :

I am using Steam Native on Arch Linux, thanks you for any help

Why are you using Wine to run the updater? DMP runs perfectly fine on Mono, so why use Wine?

Oh ok, seems logic :/ (You should precise it, and also you could precise it on the Download page because, when i downloaded it first, i saw a .exe i thought 'ok this is not working on linux')

Working now, thank you :)

(You should precise it, and also you could precise it on the Download page because, when i downloaded it first, i saw a .exe i thought 'ok this is not working on linux')

It's in the readme :P

There is no README when downloading the Updater, it downloads the .exe itself :p

Oh, I thought you mentioned the mod itself. Anyways, I'll add a note to the mod's readme then.
